drm/amd/display: Allow bandwidth validation for 0 streams.
[Why] Bandwidth calculations are triggered for non zero streams, and in case of 0 streams, these calculations were skipped with pstate status not being updated. [How] As the pstate status is applicable for non zero streams, check added for allowing 0 streams inline with dcn internal bandwidth validations.
